The Enhanced Contra Facility is for an eligible HDB owner selling an existing HDB flat and buying another HDB resale flat concurrently. HDB describes using the cash proceeds and CPF savings refunded from the sale to finance the replacement purchase under the approved arrangement. Start by identifying the exact two transactions. The facility does not describe every move from one property to another.

It helps to write Flat A for the home being sold and Flat B for the resale home being bought. Add who buys A, who sells B and which dates each person needs. The moving household is the contra party in the middle of those two transactions. Each side still needs to satisfy its own conditions. A change affecting one sale can change the other timetable.

Ask why you need the facility

A common reason is that the household needs money from the first sale for the second purchase. Identify the amount and the date when it matters. A second reason may be the desire to coordinate both transactions closely. Neither question is answered by the asking prices alone. Confirm the proceeds, eligible amounts and official timing for the actual plan.

If the household could fund the purchase without relying on sale proceeds at the same stage, compare the value of the linked arrangement with an ordinary sequence. If it cannot, focus early on whether HDB’s criteria and the other parties’ dates fit. This saves time if a different plan is needed.

Read HDB’s request page and official terms for the actual sale and purchase. HDB’s resale procedures say a buyer taking a bank or financial-institution housing loan for Flat B is ineligible for the Enhanced Contra Facility. Check any existing loan on Flat A and whether the proposed conveyancing arrangements affect eligibility. Ask HDB about the particular circumstances before assuming the application can go ahead.

Use HDB’s HFE process for your eligibility to buy and for the HDB loan assessment where applicable. Also check your eligibility to sell Flat A. Each of those matters is distinct from approval of the facility. Confirm the replacement is a resale HDB flat, and check the conditions attached to your flat, household and loan route.

Compare the financing routes with the same purchase

Suppose the household is considering both an HDB loan and a bank loan for the same replacement flat. If the bank route makes the facility unavailable, the next question is how the house purchase would be funded and sequenced without it. Compare the actual terms and the need for sale proceeds at particular dates. Do not choose on the advertised rate alone.

If an existing loan or need for separate solicitors raises a question, put that fact directly to the relevant provider and HDB. A general article can explain the shape of the facility. The answer for the actual mortgages, documents and properties must come from the official process.

Confirm all three parties can participate

HDB’s terms say the buyer of Flat A and seller of Flat B must not have applied for the facility for their respective flats. Ask HDB how to check the actual circumstances. This is an important difference from treating the arrangement as a chain that can link an unlimited number of other moves. Do not assume the other parties are eligible or using the same process.

HDB also reserves the right to withhold approval in specified situations involving mortgages, CPF charges or private solicitors, and lists some excluded types of transactions. Check your own loans and conveyancing arrangements early. A household deciding between a bank loan and the facility should compare feasible plans under the applicable terms, not assume it can combine them.

Start with the likely or agreed sale price. Deduct the amounts that need to be discharged, including the loan and applicable CPF refund, to estimate the cash proceeds. Keep the CPF refund on its own line because HDB describes both eligible cash proceeds and refunded CPF savings in the facility. Use official loan and CPF figures and check what can actually be applied to Flat B.

Include other relevant obligations and transaction costs. A sale price is different from the money left available for another purchase. Write the confirmed amounts and estimates in different columns. If a change in sale price would make Flat B unaffordable, test the lower-price case before you rely on the expected sale.

Worked example with fictional sale figures

Suppose Flat A sells for S$680,000. In a simplified example, S$210,000 repays a loan, S$250,000 is the CPF refund and S$8,000 is set aside for assumed other costs. The residual cash would be S$212,000 on those figures. The CPF refund is a separate amount. Neither the example nor the sum of the two establishes what HDB would let a particular household apply to Flat B.

Now suppose the price is S$15,000 lower while the other example figures remain the same. The residual cash would be S$197,000. Identify which planned payment that difference affects. The household might still be able to buy with more reserve, or might need a lower price on the replacement. Use the actual records for the decision.

Use confirmed figures when discussing a replacement

Start with current information about the housing loan and CPF refund for Flat A. Put the net cash after applicable obligations on a different line from the amount refunded to CPF. Check what portion can actually be applied to B under the terms. An expected amount and an allowed use of funds are two different answers.

If Flat A is still only being marketed, keep a conservative range. A higher expected sale price could make another property appear affordable before the money is established. Compare what happens if the sale price comes in lower and if the purchase price changes. Mark the amount the household can fund independently of the first sale.

List Flat B’s purchase price, any eligible HDB borrowing, the amount of CPF you can use, the funds expected from Flat A and any cash required before or after completion. Check the exact remaining lease and the value used in the relevant financing process. A flat with a lower price can still require more cash if the lease, valuation or work differs.

Separate stamp duty, legal costs, moving and essential work from the purchase price. Check HDB’s terms for which costs can be paid from which source. Confirm how earlier payments fit into the sequence. A household that can fund the completion balance may still need money for something that falls due earlier.

Make a worksheet by payment date

Start with the expected option stage, then add any applicable costs or documents needed before the exercise and application. Enter the later completion payments. After that, list the costs for getting the flat ready to occupy. Give each line a date and a source. If the facility is a condition of using a source, mark it as dependent on HDB approval.

When you compare two replacement properties, use the same categories. A home that needs less essential work may leave more room for a short overlap or early payment. Another home may better suit the household even if it costs more to move. The funding and calendar should explain the difference.

Reserve separate funds for stamp duty and legal fees

HDB’s request guidance says that refunded CPF savings and cash proceeds from the sale used through the facility cannot pay stamp duty or legal fees. Put those costs on a separate line and confirm the acceptable funding source for your case. Do the same for any payments or works outside the facility. The expected sale proceeds may be substantial and still be unavailable for a particular purpose.

Check the date when the other funds have to be ready. If an amount can be paid only after the sale or requires official approval, label the dependency. This helps you distinguish the benefit of using sale proceeds for the replacement flat from the cash required to make the rest of the transaction work.

You are selling to one party and buying from another. Ask each side about the dates it can accommodate and the steps it needs. Keep the terms and discussions separate for each property. If either side relies on another sale or purchase, confirm whether that affects HDB’s requirements and your proposed sequence.

A practical plan has a person responsible for each document and milestone. Record where the buyer of A, the seller of B, the moving household and any relevant advisers need to act. Use the current HDB process for timing. If a side has a rental or school deadline, give it a realistic place in the calendar.

Avoid giving two incompatible promises

It may be easy to tell the buyer of A that they can have a quick handover, and also to tell the seller of B that you can move at a later date. Check whether those two statements can both be true. Use the dates for legal completion, vacant possession and when B can actually be lived in. The moving household may need an interim place even if the transactions are closely coordinated.

If either outside party changes its preferred timing, update the whole plan before accepting. Find the documents and obligations affected and get the relevant guidance where needed. You can be flexible while making sure the agreed sequence remains possible.

Confirm the completion order

HDB’s terms require Flat A’s sale to complete before Flat B’s purchase completes. The events can take place on the same day. That does not mean that each household has access to the next home immediately. Put the legal sequence next to the planned physical handovers and the practical move. Check when the new home will be usable.

If one party is relying on sale funds, check which event establishes availability. An agreed intention to align the dates does not replace the actual schedule. Use the official approvals and conveyancing information. Give both outside parties clear dates for their part of the transaction through the appropriate process.

HDB links the sale and purchase applications with the Enhanced Contra request. The individual resale applications are filed separately and coordinated within HDB’s stated submission window. Use the current request page and application directions for how to record the request. Check the supporting documents and the parts each buyer and seller must complete. An application request should not be treated as approved before HDB confirms it.

Keep a note of the status for each property. If one person submits a portion, check what the other parties still need to do. If supporting documents are missing or an option timeline changes, ask how it affects the applications. The official status is more useful than a general expectation that the two transactions will proceed at the same pace.

Use a date check after every change

Suppose a lender or another party needs an extra week. Identify which option, application or completion milestone is affected. Check the applicable quota again if the change moves a resale step into a new month. Then confirm how the official procedure applies to the two linked transactions. Use the right source for the part of the process that changed.

Write down the new proposed dates and the status of each. Keep confirmed events distinguishable from assumptions. This gives the household and the other parties one consistent view of what remains to be done, while preserving the facts for each separate transaction.

Know what each party has to submit

HDB’s request guidance says the two resale applications are submitted separately, with the contra party indicating the request and the two addresses in both relevant application portions. All parties must submit their portions and supporting documents within the stated seven-day window. Read the current HDB process to see how to coordinate the submissions and identify what still needs to arrive.

Approval for the two resales does not establish approval of Enhanced Contra. Keep a separate status line for the facility. If the submissions or the financing route change, ask HDB whether the application can proceed on the same basis. Use the official status before committing to a move that depends on the linked funding.

A linked completion plan does not tell you when Flat B will be ready for furniture, work or occupation. Ask what both transactions establish about handover. If either seller wants a temporary extension of stay, read HDB’s conditions and its specific limits where the Enhanced Contra Facility is involved. HDB’s published extension terms identify the contra party as the one who may request the extension in the relevant case.

Put the formal completion and physical handover dates on different lines for each property. Then add any work needed in B and the first night it will be usable. This reveals whether the household needs storage or a temporary place even if the two legal transactions occur close together. Check approved arrangements rather than assuming an extension will be available.

A worked example of two calendars

Imagine the sale and purchase complete in the planned sequence, but Flat B still needs several weeks of essential work before occupation. A family moving from A cannot necessarily go directly to B. Check when A must be given back and what approved arrangement, if any, applies. Then price a place to stay and furniture storage if needed.

A family with a different Flat B could move sooner and avoid much of that cost. The choice is not simply between two purchase prices. It is between two moves with particular dates, condition and resources. Put those on the same page.

Make the handover credible even if both sales complete together

The owner moving from A to B should identify which keys or access they can count on and when. If B needs essential work, price a place to stay for the necessary period. If a temporary extension is being considered for A, confirm the requirements and approval before promising a date. Do not assume that use of the facility itself settles permission to stay.

Think about the timing of movers, cleaning and the delivery of essentials. A household moving with a child or older adult may need more help on particular days. Put those dates and the available help on the same schedule as the formal events.

Check what would happen if A takes longer to sell, its sale price changes or B is no longer available. A contingency plan can include a different property, another permitted accommodation arrangement or a separate sale and purchase sequence. Use the applicable conditions and do not make commitments that rely on a facility you cannot yet use.

Identify which event would require the household to act. A lower sale price may call for a revised purchase budget. A delay in B may call for a short stay elsewhere. A change in lending route may require a different way to fund the move. Put a person and date beside each possible next action.

Check the effect of one change at a time

If the sale is delayed but the price remains the same, calculate the timing effect. If the price falls but the dates are unchanged, calculate the funds effect. Then examine a case where both happen. This helps distinguish the ability to afford B from the ability to reach the right completion date.

If neither alternative works, revisit the plan before committing. The goal is to use a real fallback that can be arranged, not a line in a spreadsheet. Keep its cost and deadline beside the proposed move so you know when it needs attention.

Define when you will switch to the fallback

A family can have a credible alternative and still wait too long to use it. Decide the last day to confirm the relevant status, then work back from a date by which a short stay, storage or another property would have to be arranged. Use the requirements of both sales rather than the date that is most convenient for the moving household alone.

If a purchase depends on a particular amount from the sale, define the smallest usable sum with the actual payments on Flat B. Keep the amount you need for duties, legal fees and essential works in separate lines. A fallback should help you keep the move viable if the linked plan changes, without using money that has already been allocated to a different purpose.

Selling first can give the household more certainty about proceeds before buying. It can also create a need for temporary housing or a second move. Another sequence may have different funding and timing implications. Compare the actual options with HDB and the relevant professionals. Keep both the cost and practical effect visible.

A household might continue searching for a replacement that needs less cash upfront or is ready sooner. The alternative should still meet the everyday requirement that led to the move. For example, if the family needs a specific care route in Punggol, test another exact address before giving up the entire area.

Use the fallback to protect the better purchase decision

A credible backup gives the household time to compare the right property instead of accepting one because a date is approaching. Write down how much time the fallback provides and what it costs. If the cost is high, compare it with the value of choosing a more suitable home.

Make the same comparison if the facility is available. The shortest legal sequence may still leave the household with little room to arrange work and possession. Use the actual budget and dates rather than choosing the closest possible timetable for its own sake.

Compare the alternative in the same spreadsheet

Use the same sale and purchase estimates to test an ordinary sell-first plan. Add any temporary housing, storage and second move. Then compare the timing of funds and the flexibility it gives you. If the facility works, it may reduce one pressure. If the separate sequence suits the household better, the comparison will show which cost or deadline makes the difference.

Keep your next property requirements visible while comparing. A change in funding route should not cause the household to accept a flat that cannot serve its regular work, care or school needs. A credible fallback protects that choice.

Put A and B side by side. Include official eligibility, financing, expected cash proceeds and CPF refund, the amount you can apply, option and application dates, approval status and the two possession dates. Add the cost and date of your fallback. Give each open issue a source and an owner.

Review the record with the people who need to act. The buyer of A and seller of B may need information about their own transactions, while the household and advisers need to see how the two fit together. Use the official documents and protect private details. A good plan makes it clear which event you can count on and what needs confirming next.

Choose the first check that matters

Start by confirming whether the facility can apply to your sale and purchase. Then check the verified sale proceeds and the actual payments on B. If the funds work, confirm the two calendars and a credible handover plan. Those are the steps that turn a possible concurrent move into a plan the household can use.

Keep the final money record separate from the initial estimate

Once official figures are available, put them beside the original plan and replace the numbers that were only estimates. Confirm which proceeds and refunded CPF amounts may be used under the facility, which fees have another source, and when each payment falls due. This helps a co-owner understand why the new loan or cash amount differs from what the household expected when first viewing properties.

Then review the two addresses and the confirmed sequence. Check whether Flat A’s sale precedes Flat B’s purchase in the actual schedule and what each side has agreed about possession. The move may involve a period during which the household owns the new flat but still cannot use it. Price that period and make the plan available to the people coordinating the move.

If the facility is declined, consult HDB and the appropriate advisers about the actual applications and terms before assuming that either transaction changes automatically. Then revisit the alternative funding and housing plan. Keep the choice tied to the documents in force and the latest information from the parties.
